Molecular design of the amphiphilic AB diblock copolymer toward one-step synthesis of amino-group functionalized large pore mesoporous silica

Abstract

Amino group functionalized mesoporous silica with large pore size was obtained by one-step self-assembly of an amphiphilic AB diblock copolymer containing a hydrophobic poly(styrene) (PS) tail and a hydrophilic poly(acrylic acid) (PAA) head, a co-structure directing agent (CSDA) and a silica source. The mesoporous silica possessed hexagonal arranged ordered channels with large pore size of ca. 27.5 nm, and 3.1 mmol g−1 amino group loading amount.
